The ground was opened on 26 June 1909 as Innox Park on land that had been donated by Thomas Carr. The opening ceremony involved a parade of scholars, the singing of hymns and a speech by the chairman of the parish council.[2]

Twerton Park became Bath City's ground in 1932. A record attendance of 18,020 was recorded in 1960 versus Brighton & Hove Albion. The ground has also hosted Team Bath, who were a full-time professional team playing in the Conference South until their resignation at the end of the 2008–09 season.

From 2012-13, the stadium is to be known as the Mayday Trust Park, following a competition for renaming which raised funds for the football club.[3]

Talks have been held in the past between Bath Rugby and Bath City about sharing a ground, as the former team wish to move away from their home ground Recreation Ground, although nothing has amounted from this. Following the resignation of Chairman Manda Rigby, she claimed that the club needed to move away from Twerton Park to "sustain their finances". [4]
